Third Graders at Hoffman Trails have been learning that the Earth’s resources are limited. While recycling is important, reducing resource use and reusing items can help conserve energy needed in the recycling process. Students were asked to create a trash to treasure project in which they reused materials that would have otherwise gone into the garbage can or recycling bin and turn it into something others would want. Students considered the competition for the product(s) they created and determined a price. Students each set up a shop in their classroom and the other third graders used pretend money to purchase from the shop owners. They were both producers and consumers. This activity combined science and economic standards in a real life learning process.
